Really need what to come to!

From the tiger disaster, Chu He felt that the force value of the mountain people was still too low.

To deal with ordinary beasts or other ordinary people, the mountain people can cope with it with their strong physique.

If you deal with martial artists, or powerful evil beasts and demon beasts, ordinary mountain people are young and strong, they will not be able to do it, even if they are equipped with Mo Dao steel shields.

Refining steel bow, the difficulty is relatively large, the steps are cumbersome, the output can not be raised, and the strength required by the ten-stone steel bow is too high, and the strength of the mountain people is generally about three or four hundred catties, and it is difficult to exert the power of the steel bow.

Although, it is not impossible to raise the strength of the mountain people, as long as Chu He teaches the three exercises in front of the Golden Bell Jar, and cooperates with the strong blood elixir, it will not be a problem to increase the strength of the mountain people to one thousand, but this will take time.

The discovery of soft manganese ore has greatly increased the feasibility of large-scale assembly of steel bows in the Chu River, which can make up for the weakness of the mountain people's low force value.

The performance of alloy steel is naturally much better than that of a single high-carbon steel, not to mention that the current high-carbon steel is only made by the simmering steel method of Chu River using the soil method.

Silicon-manganese alloy steel!

With the current conditions of the Chu River, it is not realistic to manufacture spring steel.

However, with manganese ore, Chu He can find a way to refine silicon-manganese steel, and with quenching and high-temperature tempering, it may not be impossible to refine alloy steel with relatively higher toughness and elasticity.

There is no need to look for silicon, which is the second most important component of the earth's crust after oxygen, which accounts for a quarter of the volume, and gravel is mainly made of silicon.

Of course, the silicon-manganese alloy steel that is refined cannot be compared with the silicon-manganese spring steel refined by high-tech means of the earth, but the performance is definitely much better than that of high-carbon steel, and it can be used to make four- or five-stone steel bows suitable for ordinary mountain people.

Because of the lack of sufficient toughness of high-carbon steel, Chu He had to increase the thickness of the bow body and bowstring of the steel bow, with silicon-manganese alloy steel, this problem can be solved, and the specifications of the steel bow can also adapt to the change.

Of course, with silicon-manganese alloy steel, making stronger steel bows has also become a reality, or that sentence, enlarge and thicken the bowstring and bow body!

Chu He originally planned to use the method of medium-temperature tempering to build a strong bow with higher toughness for Huang Zhong, but now that he has manganese ore, he is not in a hurry, and he will wait for the silicon-manganese alloy steel to be refined before making a steel bow.

During this time, in addition to the construction and renovation of Qinghe Village, Chuhe was not idle in other things, such as small blast furnaces, tempering chambers, high-efficiency bellows, and high-quality coal, all of which were in preparation and manufacturing.

With the support of silver, these steel-making methods can naturally be implemented.

Small blast furnace or something, the construction is actually not complicated, in the past, the people who did not know a single character in Huaxia could use the soil method to make steel, not to mention the high-quality students of Chuhe, a smelting professional.

Although the coal mine Chu River has not been discovered, Datong County has a readily available high-quality coal.

Iron ore has not been found, and in the same way, Chu River can buy ready-made iron materials, but it is difficult to meet the demand for production capacity.

Chu He was overjoyed to ask Chu Shuang about the manganese ore in the underground cave, and learned that the number of manganese ore was extremely large, so he was even more overjoyed, and immediately called Chu Zhongtian and asked him to lead the way, and went to the hidden underground cave to see for himself.

Good guys, they are all good quality and extremely high content of tetragonal crystalline soft manganese ore, which is enough to meet the needs of the Chu River for a long time.

Chu He did not hesitate, and went outside to observe the terrain again, which happened to be a hidden valley basin, with an area of about two square kilometers.

The terrain around this valley basin is dangerous, there is a small stream flowing down from the mountain, usually few people come here, the entrance of the valley is a line of terrain, although it is not long, only five or six meters, but as long as the entrance is arranged to be guarded, ordinary people will never dive into this valley basin.

Chu He was worried about the construction of a small blast furnace steelmaking yard there, and now this basin happens to be used as a steelmaking site.

As long as you are careful and use trustworthy manpower, others will never think that there is a hidden steelmaking yard in the hills and woodlands more than ten miles away from Qinghe Village and close to Huya Mountain!

The most trustworthy people are naturally the people of Qinghe Village, especially the members of the village protection team and the hunting team.

In this place where the clan concept is extremely strong, the clansmen are the most trustworthy.

The overlord of Chu led the Jiangdong soldiers to dominate the world, relying on the power of the clan.

In the end, the overlord of Chu chose to kill himself by the Wujiang River, not because he was really shameless to see Jiangdong's father, but he knew that once he returned to Jiangdong, Liu Bang's army would definitely enter Jiangdong, bringing military disasters and killings to Jiangdong's fathers and elders, and making Jiangdong's lives miserable.

In the past, Huaxia used clay and bricks to build a small blast furnace at the foot of the mountain, using the iron items at home as raw materials, and using the wood on the mountain to burn charcoal, so as to remove the excessive carbon in the iron, so that the carbon content was reduced and turned into steel, which is almost exactly the same as the current situation in the Chu River.

Of course, there are many disadvantages of Huaxia doing this, first, the production conditions are too simple, resulting in the production of steel containing a lot of impurities, the standard of carbon is different, there are no professional tools, the bubble content in the steel is too large, the structural strength is low, far from meeting the application requirements.

Second, deforestation has also brought serious environmental disasters.

However, after the summary and improvement of later generations, adding some simple methods, small blast furnace steelmaking, can still refine qualified steel.

Needless to say, there are giant trees everywhere here, even if they are really cut down, with the scale of the Chu River, he can't do it if he wants to destroy the environment, not to mention that he plans to use coal with a higher calorific value to make steel.

instructed Chu Zhongtian and Sanbo to keep the manganese ore secret, and then, Chu He selected fifty young men from the village protection team and hunting team, all of whom were relatively calm and able to keep secrets, and began to build a small blast furnace in this hidden valley basin.

In addition, Chu He asked Jiang Wei to lead the team to escort the steel soldiers to Datong County, in exchange for money and silver, to buy materials in batches and many times, and send them back to Qinghe Village in a steady stream, and then secretly transported them to the valley basin.

Gan Tian rushed back to Shuangfeng Mountain after getting the steel soldiers, and as for the gold and black Puma, they were all sent as promised, and they were probably in a hurry to compete for the ranking of the Hidden Dragon List.

Of course, even if Gan Tian was still there, it would be impossible for Chu He to refine alloy steel weapons with better performance. The relationship between the two sides has not yet reached that point.

The matter of steelmaking and manganese ore refining is proceeding in an orderly manner.

Chu He felt that his triple rock body protection was not safe, and during this time, he also took time to step up his cultivation, and began to boil the strong blood elixir, and cultivated the second heavy wood and stone body of the Golden Bell Jar.

After a period of accumulation and preparation, whether it is steelmaking or cultivation, it seems that it is about to enter the channel of high-speed development.

Seeing that the medicinal liquid in the medicine pot continued to evaporate and concentrate, the smell emitted, and the color and concentration of the medicinal liquid, etc., were exactly the same as what the cheats said, Chu He knew that this third pot of strong blood medicine could be refined.

The concentrated medicine is added to rice flour, syrup, propolis, etc. to absorb the medicinal juice and turn it into a paste, and finally it becomes a pill.

The difference is that the elixir is directly used to soak the body, and the elixir can be used to take it, which is easy to preserve.

When the medicinal juice is boiled, Chu He removes the medicinal residue and adds propolis rice flour to it, heats it for a while, and the ointment is generated.

Pinch it into a pill the size of a pigeon's egg while it is hot, take the next one, and feel the medicinal power in the pill, Chu He's face suddenly became happy.

It's time to bring the big steel buckets and steel kettles specially made by the Chu blacksmith to visit the Tiger Bee brothers in Huya Ridge.
